A ref. 4300V/120R-B547 Overseas Perpetual Calendar Skeleton, the culmination of VC’s integrated-bracelet sports watch and ultra-thin perpetual calendar history. The Overseas line, born of the legendary 222, has debuted numerous complications over its three generations, but was only first offered as a perpetual calendar in 2020. Vacheron built upon their storied 1980s ref. 43031 Perpetual Calendar, forming a bridge between two highly successful threads of their history by evolving the same 1120 QP movement. Here, extensive skeletonization opens up that 1120 QP for a glimpse of Vacheron Constantin’s utmost technical and finishing ability, deserving of the Geneva Seal it proudly wears. The Overseas Perpetual Calendar Skeleton epitomizes modern Vacheron Constantin: technical complication, exquisite handwork, refined design, and a beautiful, timeless heart.
